Background: Although trunk muscles are involved in many important functions, evaluating trunk muscle strength is not an easy task. If trunk muscle mass and thickness could be used as indicators of trunk muscle strength, the burden of measurement would be reduced, but the relationship between trunk muscle strength and trunk muscle mass and thickness has not been clarified.
Objective: The purpose of this study was to clarify the relationship between trunk muscle strength and trunk muscle mass by bioelectrical impedance analysis and trunk muscle thickness by ultrasound imaging in healthy adults.
Article Synopsis
- - A recent study isolated a mutant plant with extra stromules in leaf cells, identifying the responsible gene as a regulator for chloroplast division, linked to specific mutations at the gene's ends.
- - Further analysis found that this gene plays a vital role in shaping plastids across different leaf cell types, revealing abnormal plastid forms in pavement, trichome, and guard cells.
- - The research also demonstrated that the mutant lines displayed various plastid abnormalities but maintained certain plasticity in trichome and guard cells when compared to other severe mutants, suggesting distinct roles in chloroplast morphology.
